Recommended no drain acid wash?

[reggie ho]

Hi all,

Is there a preferred no drain acid wash from the experts on this forum? Hoping to avoid draining the pool and removing some tough scale the hard way. (Have tried keeping CSI between -0.3 and -0.6 and brushing but no luck. Even a pumice stone didn't have much luck with the stuff I have.)

Any of these that are particularly good? or to be avoided?
Jack's
United Chemical (amount of acid they recommend adding concerns me)
Scaletec (not sure if this is actually a no drain acid wash)

Thank you,

Patrick

Are you planning to do it or have a pool company do it?

We have had quite a few folks here have their plaster damaged by acid washings.

Planning to do it myself but hoping to avoid a full drain and acid wash. My impression was that these no drain options were less harmful/likely to cause damage as well, but please let me know if this isn't true. Thank you

2nd times a charm.......No Drain Acid Wash

Just completed round two of a "no drain acid wash". Used 8 gallons of acid this time and after 2 days all issues with scale and/or plaster dust have been resolved! The pool now looks better than ever before since being built in 2006. Thanks to everyone for their input on this topic!

trying a non aggressive no drain acid wash

Opened my pool in early may to calcium scale that trapped dirt under it. At one point the entire bottom of the floor and all of my steps were stained. Recently I lowered my PH to 7.2 and held it there for a week. I am making progress and I believe if I held my PH to low normal for the entire...

no drain acid wash

I just completed a no drain acid wash on a marcite pool (16,000 gallon) using 12 gallons of muiratic acid over the past two days. It removed all the copper stains after brushing with a steel bristle brush and the pool surface looks as good as when I had it remarcited. The water is cloudy I...

No Drain Acid Wash

For the last few seasons, I've seen more and more evidence of pool bottom and wall scaling. The pool is 10 years old (24K gallon), and the water comes from a well (which is hard to begin with). It's getting so bad, that swimmers come out of the pool with their feet bleeding. Very rough...
